+#### Troubleshooting Operator installation
+Sometimes deleting the previously installed Operator package will fail to remove all operator pods. To troubleshoot this ensure these following steps.
+
+1. Make sure that all the other deployments or helm release is deleted (purged). Operator package is a baseline package for the applications, so if the applications are still running while trying to delete the operator package might result in unwarrented state.
-#### Install Collection package
+2. Delete all the resources and CRDs associated with operator package.
+```bash
+#NOTE: Use the same release name and namespace as in installation of operator package in the previous section
+cd $DA_WORKING_DIR/operator
+helm template -n operator . -f values.yaml --namespace=operator > ../delete_operator.yaml
+cd ../
+kubectl delete -f delete_operator.yaml
